1) установка зависимостей

sudo apt install libssl-dev
sudo apt install gcc
sudo apt install make
sudo apt install minicom

2) распаковка архива

tar xvfz moxa-real-tty-linux-kernel-5_x-driver-v5_2.tgz
cd moxa

3) запуск скрипта установки

sudo ./mxinst

Результат:

Installation process is completed.
The all driver files are installed on /usr/lib/npreal2/driver.

4) Now you can cd /usr/lib/npreal2/driver and run ./mxaddsvr to add tty port.

./mxaddsvr 10.10.10.238 1


Adding Server...
ttyr00, cur00
Added RealCom server: ip : 10.10.10.238
mknod -m 666 ttyr00 c 33 0
mknod -m 666 cur00 c 38 0
Complete.

5) Проверить текущие COM порты

dmesg | grep tty

[    0.469616] printk: console [tty0] enabled
[2421173.422369] [   1358]     0  1358     1457      380    49152        0             0 agetty

[2436692.909521] MOXA Async/NPort server family Real TTY driver ttymajor 33 calloutmajor 38 verbose 0 (Ver5.2)
6) настройка прав на чтение/запись

First have a look at the permissions on that file
ls -l /dev/ttyr00
 sudo chown admin /dev/ttyr00

You will want read.write access, if this is a shared system then you should consider the security consequences of opening it up for everyone.
sudo chmod o+rw /dev/ttyr00
sudo usermod -a -G tty admin
sudo chgrp tty /dev/ttyr00
sudo chmod 666 /dev/ttyr00

7) minicom

экран настроек приложения с параметром -s
minicom -s

Для подключения к устройству
 sudo minicom -D /dev/ttyr00

Для выхода:CTRL+A → Z → X
8) Отправка данных в com-порт

A very simple crude method to write to the file, would use the simple echo command.
echo -ne '\033[2J' > /dev/ttyr00

to read
cat -v < /dev/ttyr00

9) Команда удаления

cd /usr/lib/npreal2/driver
./mxdelsvr <IP>
